basic information
The auto-calibration function is a feature that aligns the values of the light sensor inside the brightness box (the reference value for reproducing brightness) with the LC-5. It is effective in the following situations: 1) Simple calibration when you have multiple brightness boxes. 2) Regular simple calibration of the brightness box. 3) Aligning with the values of the brightness meter you own. Brightness boxes that support auto-calibration are equipped with an "LC" connector. A dedicated cable is used to connect the brightness box and the brightness meter.
